Re: "Good OHM'n"... here we go...
I picked up this Ogura electric clutch on the weekend also. I plan to use it for my regenerative breaking alternator. I will mount it on the motor aux shaft and energize it from a thumb switch on the side of my shifter knob. It had a tapered mount hole. I bored it out to 7/8" to fit my aux shaft but need to broach a keyway now.
I may end up moving my motor speed sensor to the drive shaft end, just behind the coupler. We'll see. Been messing with it.
